This invention relates to pressing machines as garment and laundryressing machines, such as are used in c othing factories, tailor shops,knitting mills, laundries, etc., and it especially has for its object aparticularly simple and efficient and durable and also pedallessmechanism by which the power, if applied when the press is open, isineffective on the movable pressingelement or head, and by which theclosing of the :press or the movement of the movable presslng element orhead toward closed position a predetermined distance by handisi'nefi'ective on the power mechanism, in other words the invention hasfor its object an arrangement of parts of a motion transmissionmechanism whereby if the power mechanism is actuated when the pressis'open, the motion thereof cannot be effectively applied or transmittedto the pressing element or head or whereby no motion can be elfectively'transmitted unless such head has been preliminarily brought .down towardthe work by the operator or close to the work to a whic press beingsafety first position, before the power is connected.to' the formermechanism. By safet first position is meant a position in the operatorcannot have his hands between the pressing elements.

The invention consists in the novel features and in the combinations andconstruc-' tions hereinafter set forth'and claimed.

In describing this invention, reference is had to the accompanyingdrawlngs in which like characters designate corresponding parts in "allthe views.

This pressing machine comprises, generally, coacting pressing elements,one movable toward and from the other, a carrier supporting the movableelement, a power member, motiontransmitting connections between saidmember and the carrier, said connections including parts normally out ofposition to effectively transmit the motion of the power member to thecarrier when the press is open and movable into position to effectivelytransmit the motion of the ual means as a handle on the carrier or themovable element to so move the movable. element into preliminary closedposition and means including a-second handle for controlling theactuation of the power member. The power member is intermittentlyactuated'by means as an electric motor and the second handle controlsthe intermittent actuation of the power member.

1 and 2des-1gnate the pressing elements which are here shown as aso-called lower buck and an upper press head movable toward and from thebuck, the buck 1 being usually stationary and carried by the bracket orso'-called goose neck 3 which in turn is mounted upon a table 4 suitablysupported by a frame 5. i

The upper press head 2 is here shown as supported by a movable carrieras a lever or yoke 6 pivoted bet een its ends at 7 to a 1standard'8iextendin upwardly from the a suitable counterweight 1 0 and also usuallyhas connected thereto a spring 11 acting in conjunction with thecounterweight. The counterweight 10 and spring 11 constitute to open thepress when no force is apphed or active. tending to close the press orhold'it closed. The handle 9 is a manual means for preliminarily closinthe press against the counterweight 10 an spring 11 or other meanstending to open the press, and for holding it closed until the powermemberis actuated.

12 designates the power member which is here shown as a lever pivoted at13 between its ends to the lower part of 'the frame near the floor, thispower lever extending forwardly and rearwardly of the machine. The

power. lever-is actuated by an intermittently.

movable motor driven actuator as will be hereinafter described.

The connections between the power lever 12 and the carrier lever 6, areconstructed to be inefi'ective to transmit the motion of the power lever12; if actuated when the press head is up and 'also ineffective totransmit the motion of the carrier 6 to the lever. 12 when the press isbeing closed or the press head 2 is being moved a predetermined distancetoward closed position by the operator.

These connections comprise links 14 and15' of the power lever 12 isefliective 0n the carrier 6. These connections further comprise meansfor preventing the toggle links from unfolding when the lever 12 isactuated and after the links 14 and 15 have been moved into or nearlyinto or toward the'dead center line of the toggle links 14 and 15 bysuch closing movement of the head 2.

The link 14 as here shown, is pivoted at 16 to the rear arm of thecarrier lever 6 and the link 15 is pivoted at 17 to the rear arm of thepower lever 12. The link 15 extends rearwardly from the power lever 12when the press 1s open, and is movable into a position at or nearly at aright angle to the lever 12 when the head 2 has been pulled down by handtoward closed position a predetermined distance. The lost motionconnection between the links 14 and 15 is of such a nature as to merelymove the link 15 from its normal nearly horizontal position, Fig. 1,into a position approaching a right angle to the lever 12 when the head2 is ulled down by the operator, so that the inks 14 and 15 idle duringthe closing of the press head 2 by the operator, or when the power lever12 is actuated before the head is pulled down.

This lost motion connection is preferably a pin 18 provided on thelowerend of the link 14 and a lengthwise slot 19, in which the pin worksin the link 15, the pin moving downwardly in the slot. and liftin thelink into vertical position durin ownward mo ement of the press head byand, so that,

when the press head has been. closed a predetermined distance byhand thepin is at the lower end of the slot and hence, when the power isappliedto the lever 12, the link 15 or bottom of the slot 19 thrustsupwardly against the pin 18 and thrusts the link 14 endwise upwardly andforwardly and rocks the carrier lever 6 on its pivot to apply comparatively heavy pressure to the head 2. The bottom end wall of the slot19 and the pin 18 constitute shoulders normally out of abutting relationand movable into abutting relation by the preliminary closing of thepress head 2 by hand.

As the lever 15 is pivoted loosely at both of its ends and also as thelever 14 is pivoted loosely at both of its ends, means is pro- .videdfor preventingthe unfolding of the links 14 and 15 at the pin and slotjoint 18, 19 when the power is applied to the lever 12 after the presshead 2 is closed or brought down by hand a predetermined distance. Thismeans, as here shown, consists of a third link 20 pivoted idly orloosely at the lever 14 and to the frame and being arranged out ofparallelism with both links 14 and 15 when they are in any position andparticularly when they are in straight position or nearly straightposition. The link 20, as here shown, is pivoted at 21 to the link 14above the pin 18 and at its other end to the frame preferably coaxiallywith the power lever 12 or on the same pivot or shaft 13that the powerlever is mounted on, although such link 20 may be differently arrangedtojguide the links 14, 15 during the application of power to the powerlever 12. The link' 20 being mounted on a different center from the link15 which. causes its pivotal point 21 to move in an arc having adifferent curvature from the arc of movement of the pin 18L Obviouslyduring the movement of the press head 2 downwardly by hand from theposition shownin Fig. 1, toward that shown in Fig. 2, the links 14, 15and 20 will move nearly into their position occupied in Fig. 2, andduring such movement the pivot points 18 and 21 y will move in the arcmm and y-y respectivelyn As the links approach their posi- 11 tion shownin Fig. 2, the arc g having a greater forward and upward curvature thanthe are 00-60, obviously the pressure is applied through the act of thetoggle consistmg of the links 14 and 20 and the link 15 tends to movethe links- 14 and 20 toward the dead center line passing through thecenters 13. As seen in Fig. 5, the link 20 is double and embraces thelinks 14, 15.

It is the movement of the links 14, 20 toward their dead center line orthe movement of the pivot 21 in the arc y-y that applies the pressure tothe head 2.0r carrier 6, and the toggle consisting of the links 14, 20is actuated by the power lever 12 through "the 139 additional or secondlink 15 which is a thrust link pivotally or foldably connected to thepower lever 12, and to one of the toggle links 14, 20, it beingconnectedto one of the partsto which it is connected by a lost motion,or pin and slot connection arranged to be taken up by the manualmovement of the head 2 and the carrier 6 a predetermined distance towardclosed position and the consequent movement of the links 14, 20.

If the power is applied to the lever 12 before the head 2 is broughtdown to a predetermined position, these connections consisting of theparts 14, 15 and 20, will at the most again move the head upwardly oropen the press instead of closing it. r If the ower is applied to thelever 12, 'while the iiead is open practically no motion will betransferred to the head or at the most a slight oscillating movement. Ifdesired", in

order to prevent the head from being ac- -gaged with the lever.

tuatedrat all from the power lever 12 until the head has been broughtdown to a predetermined position, the'rear side of the slot 19 may beomitted or the slot widened, as shown, in Fig. 7 or the lever 15 maynormally stand in starting position, nearthe effective position thereofor inclined slightly out of vertical, as shown 1n Fig. 8, and be pickedup ,by the link 14 when the head 2 has been pulled b hand apredetermined distance and move by the link 14.

The link 14 is adjustable endwise' to per 'head 14, and the'wheel turnedin one direction or the other, the wheel is then again shifteddownwardly so that the socket receives the head, and hence holds thewheel and the rod from turning.

The power lever 12 is preferably actuated in one directionby motorpower, the appli-, cation of which is controlled by an'additionalhandle, which must be operated while the operator has hold of the handle9, and as here shown, it is actuated from a con stantly running electricmotor by an inter mittently movable cam, which is always en- The powerlever is actuated in the other direction by a spring 12* which-carriesthe lever 12 to follow the cam. Y Y i 22 designates the cam which iscarried 1 by a shaft 23, the cam being here shown as an eccentricallymounted pin having a roller 24 thereon, which en ages a wearing face 25on the front end o the lever 12. The lever pressed is held against theroller to follow the same by the spring 142 This shaft 23 is journalledin suitable bearings 26 carried by a suitable casing .27 supported by'abracket 28 carried by a frame member29, and is actuated intermittentlyone-half revolution by a; motor supported on the frame and having itsshaft '31 or extension thereof provided with a -wor;n 32 meshing with aworm gear 33 mounted to rotate about the shaft 23- and to beconnectedthereto and disconnected therefrom periodically by a halfrevolution or periodic clutch designated generally 34. This clutch isoperated by a suitable hand lever 34 which is operated by the operatorwhen the head 2 is brought down. If this leveris operated to throw theclutch before the head is brought down.

the cam makes a half revolution and actuates the leverf12 but themovement of the lever 12 is inefiective on the carrierlever 6 on accountof the operation of the toggle links 14, 15-and 20, as before explained.However, the machine is now out of synchronism or seqlyice, as thepower. lever ,12 is deand the. press is open while in V the pr persequence the power depressed when the press is closed- In order torestore thesynchronism' or sequence it is necessary to again operatethelever- 34" to connect the clutch 34 tothe worm gear 33, so that theclutch in'making a half revolution will againrotate the cam 22 a halfrevolution. v

The clutch 34 maybe of any suitable form, size and construction and theconstruction thereof per-se forms no part of this invention. It issufficient to bear in' mind that the clutch is operated by the operatorto connect the ccnstantly running motor to the cam shaft 23 andisautomatically disconnected when. the cam has made arhalf revolution.

The clutch here illustrated comprises an axially shiftable disk orcarrier 35 having a hub 36 mounted to rotate about the shaft 23, afloating thrust ring 37 opposed to the disk 35, a guide 38 between thethrustring 3? and the worm gear 33, a plurality of plns 4O slidableinalined openings in the guide disk 38, thrust ring 37, and carrier disk35, these pins having shoulders 41 against which the thrust ring 37thrusts, one or more springs, as 42, tending to separate the thrust ring37and the carrier disk 35, a main spring 43 tending to shift the ring 35in one direction, as to the right, to dis connect the clutch, manualmeans for shifting the ring 35 to the left against the spring 43, andmeans for holding the carrier rlng 35 in itsimanually shifted positionduring the half revolution of the clutch. The gear wheel 33 isprovided'with a circular series of holes 45 for receiving the pins 40and thus locking the gear wheel 33 to the when the pins are registeredwith the holesguide ring 38 which guide ring is keyed to the shaft 23.As here illustrated, the gear wheel 33 is mounted on a hub 46 on oneside of the guide ring 38 and the guide ring has another hub 47 on theother side thereof which is keyed to the shaft 23 as by a transverserkey48. I

The means for shifting the clutch, as here shown, comprises a shifter orrock arm 49 mounted on a rock shaft 50 journalled in the casing 51 ofthe clutch, this rock shaft being operated to the left by the lever 34and connections controlled by said lever. The arm 49 thrusts against oneend of the hub 36 of the carrier ring 35 and when rocked in onedirection serves to shift the carrier. to the left;'and. the carrierserves to shift the thrust ring 37 through the springs 42 to the leftand thus move the pins in the openings into the gear wheel 33. In theevent the pins 40 do not register with the holes 45, the springs 42compress or yield and then,

45, react and thrust the pins 40 into the holes 45. Thus the lever 34can be thrown to its full extent by the operator regardlessof whether ornot the pins 40 are alined with the holes 45. I

The means for holding the ring in its shifted position until the clutchhas made a half revolution comprises a' circular track 52 supported bythe cover or the case 51 concentric with the shaft, 23 and havingnotches 56 preferably diametrically opposite each other for receivingthe followers or rollers 57 on the carrier 35. Upon operating the shaft50, the carrier 35 is thrust to the left carrying the rollers 57 out ofthe notches 56, so that the clutch now being engaged will start on itshalf revolution and the rollers will ride on the face of the ring 52until the rollers again come into alinement with the notches 56 afterthe clutch has made a half revolution. When the clutch has completed itshalf revolution, that is, when the rollers have a ain come intoalinement with the notches 56, the spring 43 thrusts the carrier 35 tothe right to carry the rollers 57 into the notches 56.

The connections between the lever 34 and the rock shaft' for shiftingthe clutch 34, comprises an upwardly ez'rtending arm 58 on the rockshaft 50, a rock shaft 59 supported in a suitable bearing in the upperend of the frame 5 near the table 4, a rock arm 60 on such shaft 59, apawl 61 pivoted at 62 to the rock arm 60 and having one end arranged toenga e the lever 58, the lever 34 being mounte upon the rock shaft 59,and a spring 63 tending to rock the shaft 59 in the direct on oppositeto that by which it is rocked by the lever 34. Upon depression of thelever 34 the rock shaft 59 is rocked in one direction as to the rightmoving the rock arm 60 thereon to the right, causing the end of the pawl61 to engage the upper end of the arm 58 and move such arm to the rightand thus rock the shaft 50 to shift the shifter arm 49 to the left andhence shift the carrier ring 35 of the clutch 34 to the left to engagethe clutch or shiftit to 'in position. The clutch is held in in positionby the track 52 as heretofore described and when the lever 34 isreleased the spring 63 returns it and the shaft 59 to its-normalposition. As the arm 60 swings in an arc upwardly away from the arm 58,the pawl in passing upwardlypasses out of engagement with the arm 58,this occurring after the clutch 34 has been thrown in. Duringretrogrademovement of the shaft 59 and the lever 34', the pawl 61 slides over theupper end of the arm 58. Pivotal movement of the pawl 61 is'preventedwhilethe pawl is operatingor thrusting against the arm 58, by a shoulder64 on the arm 60 which shoulder engages the tail of the pawl 61. The arm58 is inclined to the left and the weight thereof moves it to its normalposition as soon as it is free of the pawl 61. However, the thrust ofthe hub 36 of the carrier ring 35 of the clutch 34 to the right by themain clutch spring 43 would also return this lever 58 to its normalposition.

At an intermediate point between the positions occupied by the head 2when it is open and the'position occupied when pulled down by hand to apredetermined position, the toggle mechanism, is at such a point forconvenience called a neutral point, that if the power were applied fromthe lever 12 the head 2 and the lever 6 would be thrown upwardly with amore or less violent jar due to the toggle links 14, 15 and 20 unfoldingbackwardly, or the head might be thrown down by power.

In-other words there is an intermediate or neutral point which the head2 and the lever 6 may occupy between open position and a predeterminedclosed position, where if the power were applied from the lever 12 thelinks 14, 15 and 20 would hesitate on account of the small leveragewhether to unfold and open the press or to continue towar l straightposition and close the press.

In order to prevent the application of the power at such intermediate orneutral point, means is provided for preventing the operating of thelever 34 until the press head has been pulled down by hand beyond suchintermediate or neutral point. Such means would be unnecessary after theoperator learned to pull down the head to such predetermined point. Suchmeans comprises a lock operable to lock the handle 34 from operationwhen the press head and parts moved thereby are in such intermediate orneutral point. The lock comprises a rack 65 on a sector or arm- 66mounted on the shaft 59 to rock therewith, and an endwise mov- 13,

ment of the lever 6 or some part movable with such lever as the togglelink 14, the rod 67 having a tooth 68 arranged to be moved intoengagement with the rack 65 when the links 14 and 15 are at or near suchintermediate or neut-ral'point. As here shown, the rod 67 is carried insuitable guides 69, carried by the frame and is pressed rearwardly sothat its tooth 68 will engage the rack 65 by a spring 70 and is pressedout of engagement by a cam 71 on the link 14. This cam has high points72 and 73, and intermediate low point 74 between the high points. Thehigh points 72 and 73 press the rod forward to hold the tooth 68 out ofengagement with the rack 65 when the press head is open and during itsmovement toward such intermediate point, and after the press head haspassed such intermediate point; and the low point 74 of the cam permitsthe spring 70 to move the rod 67 endwise rear-wardly and hence engagethe tooth 6.8 with the rack 65 when the head is in the neighborhood ofintermediate point. Thus when the head is open, thelever 34 can beoperated, and the cam 22 actuated to depress the lever 12, but the link15 idles and very little or no move- Iiient will be transmitted to thepress head. And when the press head is pulled way .down to apredetermined point and the lever. 34 is actuated, the motion of'thelever 12 will be effectively transferred to the press head '2 But if theoperator neglects to pull the head down a predetermined distance, theoperating lever 34" is locked so that the clutch 34 can not be thrown tocause the cam 22 to actuate the lever 12, the lever 34" locking when thehead is pulled down to an interme: diate position, and not to .apredetermined or fully closed position, by the fact that the lock rod 67is opposite the .low point 74 of the cam 71 and is-moved by the spring70 to the right, Fig. 4, carrying the shoulder or tooth 68 into meshwith the rack or sector 66 .on the shaft 59 which is actuated by thelever 34*, and thus locks the shaft 59 from being rocked.

A. suitable buffer is provided for limiting the opening movement of thehead. This buffer may be provided between the frame'lever 6 and-the mainframe 5 near the pivot 7, of the lever 6, or to coactiwith any partmovable with the lever 6. As here shown a buffer is provided on theinterme diate part of the lever 20 and engages a stop surface on therear arm of the power lever 12. i

75 designates thebufier on the lever 20 .and 76 a stop surface on therear'end of the lever 12, the buffer 75 coming in contact with the stopsurface 76 when the press is.

open, as shown in Fig. 1. However in the illustration of the togglemechanism, shown in Figs. 7, and 8, t e buffer preferably located as at77, between the forwardly extending arms 78' of the counterweight andthe opposite surface of the standard 8.

In the operation of the machine, assuming that it-is in the positionshown in Fig. 1, the operator places the garment 'or other article onthe lower buck, takes hold of the handle and pulls downwardly thereonmovthe head 2 toward the buck, so that, there is very littlespacebetween thehead-and' the work on the lower back. Such movementcarries the links 14, 15 and 20 from their, inactive position shown inFig. 1 to near but not quite their effective positions shown in Fig. 2.The operator then -depresses the 80 lever 34 throwing in the clutch 34and thereby connecting the motor to the cam shaft 23, whereby the cam 22makes a half revolution to the position shown in Fig.2, thus depressingthe lever 12 which in turn 'moves' the links 14, 15 and 20 into the posi12 and holds the pressure as long as desired.

When the lever 34 is again operated to throw in the clutch 34, theclutch 34 makes another half revolution from the position in Fig. 2, tothat shown in Fig. 1, permitting the spring 12? to pull the lever 12upwardly and causing the,lever to follow the cam 22, and also permittingthe counter weight 10 and spring 11, to open the press.

As the lever '12 follows the cam 22 during the opening of the press, theopening of'the press is controlled by the cam so that the press opensevenly and without jar or shock,

The pressis particularly advantageous in that it is pedalless and mustbe closed by one hand, to a safety first position before the powercontrolled by the other hand, can be effectively applied thereto, and inthat it operates evenly as the actuating cam is constantly engaged withthe power lever and no lock and latch, mechanisms are necessary to holdit preliminarily in safety first position or in final pressing position.
